LAMP-BURNER.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed June 8,1907. Serial No- 377,870.

To all whom it may concern:

Be it known that I, GEORGE W. GIBBs, a citizen of the United States, residing at Ronceverte, in the county of Greenbrier and State of West Virginia, have invented a new and useful Improvement in Lamp-Burners, of which the following is a specification.

My invention relates to lamp burners of that type which are provided with extinguishing attachments.

One form of such lamp extinguishers consists of an oscillating arm arranged beside the Wick tube and having at its upper end a horizontal angular wing on a level with the top of the wick tube which is adapted, by the oscillation of its arm, to be thrown directly over the top of the wick tube and wick, to extinguish the flame, or be adjusted laterally away from the wick tube when the lamp is burning. For the adjustment of such extinguisher it has had its lower end bent around the ratchet shaft with a frictional engagement, so that when the wick is turned down the same movement will apply the extinguisher to the top of the wick, to put out the flame, and when the wick is turned up, the extinguisher is by the same movement Withdrawn from the wick. In this form of extinguisher a difliculty has been experienced, in that an opening through the foraminated base plate of the burner must be made large enough to allow the extinguisher to play back and forth, and this opening allows a strong current of air of large volume to pass up on one side of the wick tube through said opening, which extra current of air, being on one side of the wick tube only, destroys the balance of the flame, causing it to flicker and flare, with the result that it does not give a steady light, but is deflected over to one side depositing carbon on the cone.

My invention is designed to obviate this difliculty, and to that end it consists in forming a closed pocket for the extinguisher, which pocket opens upwardly through the ioraminated base plate to house and contain the extinguisher and give room for its play, without any passage for the uprising current of air, all as hereinafter fully described with reference to the drawing, in which Figure 1 is a central section through my burner when closed and Fig. 2 is a view showing the cone thrown back and the foraminated base plate broken away to show the pocket containing the extinguisher.

In the drawing, A represents the foraminated base plate, on which the chimney rests and through the small perforations in which plate streams of air rise in such uniform distribution as to make a steady flame.

B is the screw threaded bottom piece which screws into the oil font. This bottom piece is connected to the foraminated base by divergent arms b.

C is the wick tube firmly secured in both the bottom piece B and the foraminated plate.

D is the ratchet shaft arranged in bearings in the bottom piece B and having the usual ratchets or toothed wheels d which pass through slots in the wick tube and engage the wick to turn it up and down.

E is the cone, hinged to the side of the foraminatcd base and e the spring arms for holding the chimney.

F is the extinguisher arm whose lower end is provided with a frictional spring clamp f that presses on the wick adjusting shaft with suflieient frictional engagement to cause the arm to swing in the direction the shaft is turned. At the upper end of the extinguisher arm is the right angular and horizontal wing a that is on a level with the top of the wick tube and is adapted to pass over the top of the wick to extinguish the flame.

As so far described the burner and extinguisher are of an old construction.

In my invention, I provide a pocket I for the extinguisher to play in. This pocket is formed by a collar band of sheet metal which preferably embraces the wick tube and is joined at its upper edges to the bottom of the foraminated base plate A and at its lower edges it is closely united to the base B, so as to form a perfectly closed pocket at the bottom and sides, but opens at the top through the foraminated plate. This prevents a large volume of air from rising on the side of the wick tube and allows the flame to be fed only by the stream of air rising through the minute and numerous perforations of the foraminated plate A, securing a steady and uniform flame.

I claim 1. A lamp burner having an extinguisher arm pivoted at its lower end and provided with an angular horizontal wing at its upper end, and an imperforate pocket closed at the bottom and sides and open at its upper end and inclosing the lower portion of the extinguisher arm.

2. A lamp burner, comprising a foraminated base plate, a wick tube with ratchet shaft beside it, an extinguisher arm pivotally secured at its lower end about the ratchet shaft with a frictional engagement and having at its upper end an angular horizontal wing arranged at the upper edge of the wick tube, a pocket inclosing the lower end of the extinguisher arm and at its upper edge connected closely to the foraminated base plate and opening through the same.

3. A lamp burner, comprising a foraminated base plate, a screw threaded bottom plate, a wick tube connected to both, a ratchet shaft arranged in hearings in the screw plate and having ratchet wheels entering the wick tube, an extinguisher arm pivotally secured at its lower end about the ratchet shaft with a frictional engagement and having at its upper end an angular horizontal wing arranged at the upper edge of the wick tube and a tight pocket inclosing the lower end of the extinguisher arm, said .pockct consisting of a collar band joined at its lower edge to the screw bottom plate and at its upper edge to the foraminoted base.
